"Race organisers for the forthcoming United States Grand Prix in Austin, Texas, have released a draft layout of the new circuit that will stage the event from 2012, when Formula One racing returns to the country for the first time in five years.

Working with renowned track architect Hermann Tilke, organisers Full Throttle Productions LP have drawn inspiration from the best circuits around the world, as well as taking advantage of the site’s natural topography to include some dramatic elevation changes.

“The area has natural elevation differences, which promises a fast track with difficult corners,” Hellmund told Formula1.com recently. “But the most essential thing is that has to be a masterpiece in its suitability for fans. Spectators have to be able to see large parts of the track from wherever they are.”

The 3.4 mile (5.47 kilometre) circuit features 20 turns and a total elevation change of 133 feet (40.5 metres), including a steep, uphill run into the hairpin Turn 1, which is expected to become the venue’s signature corner. In common with just three other current F1 venues - Istanbul Park, Abu Dhabi's Yas Marina Circuit and Interlagos in Brazil - it will run in an anticlockwise direction."
